Below is everything I have concerning these connections, the NUL-MODEM pinout is downloadable in the DR480 manual:

Try products from B&B electronics www.bb-elec.com
Its a USB to 422 converter at house model# us422tb
this converts to 422 I chose 422 for its stable bi-directional point to point protocol. this unit is usb port powered.

The stage receiver is a optically isolated 422/485 to 232 converter model# 485ot9l. this unit needs a wall wart power (because its optically isolated) people were very helpful steering me the right way. paperwork between the two devices was a little contradictory but very informative and written well. needs 2 twisted prs to work. has been flawless I think it was $250 + - for the pair

Below is a definition of the cable pinouts and functions for the drive rack.

RS-232 DB-9 Male

1. N.C.
2. Recieve Data (From PC to 480)
3. Transmit Data (From 480 to PC)
4. Pulled Hi
5. Ground
6. N.C.
7. RTS (From 480 to PC) (Optional)
8. CTS (From PC to 480) (Optional)
9. N.C.
Chassis. shield

Note: For a minimum configuration cable, you will need Pins: 2, 3 and 5. The drive rack is concidered a master so to interface to a PC the cable should have pins 2 and 3 crossed.

If you are running long cables It will be helpfull to use a shielded cable. Connect the shield to the chassis of the connector at both ends.

BACKBONE DB9 Female (In and Thru)

1. Tx/Rx +
2. Tx/Rx -
3. Signal Termination LED's
4. Signal Termination LED's
5. N.C.
6. N.C.
7. Ground
8. Chassis Ground
9. N.C.

Note: This as a half duplex connection so Both recieve and transmit occur on the same 2 balanced lines (Pins 1 and 2). Pins 3 and 4 are used to control the Termintation LED's on the back panel and have nothing to do with the RS-485 signal.

Backbone RJ-45 (In and Thru)

1. Tx/Rx +
2. Tx/Rx -
3. Signal Termination LED's
4. Signal Termination LED's
5. N.C.
6. N.C.
7. Ground
8. Chassis Ground

REMOTE CONNECTIONS

480 \"Controller in\" DB9 Female

1. Rx+ (From 480P to 480)
2. Rx-
3. Tx+ (From 480 to 480P)
4. Tx-
5. N.C.
6. N.C.
7. Ground
8. N.C.
9. N.C.

480 \"Controller in\" RJ-45

1. N.C.
2. N.C.
3. Rx+ (From 480P to 480)
4. Rx-
5. Tx+ (From 480 to 480P)
6. Tx-
7. N.C.
8. N.C.

Note: The connection between the 480 and the 480R is a Full Duplex connection. This means that there is a balanced Pair of wires for each direction. Since this is a point to point connection, the terminators are built into the units.

480P to 480R Connections
480P DB-9 (to 480R)

1. Tx+
2. Tx-
3. Rx+
4. Rx-
5. Ground
6. +36V Power
7. N.C.
8. +36V Power
9. Ground

480P DB-9 (to 480R)

1. +36V Power
2. +36V Power
3. Tx+
4. Tx-
5. Rx+
6. Rx-
7. Ground
8. Ground

Note:The diagram on the bottom of Page 108 in the owners manual refers to a cable with RJ-45 connectors only.

It is strongly recommended that you use the cables provided by dbx for running between the remote and the power supply. tested and are capable of delivering the power with minimal voltage drop and of transmitting the appropriate RS-485 signals with no Data corruption.

    For network and GUI connections, use a USB to 422 converter (model# US422TB from B&B Electronics) for stable bi-directional communication, powered via the USB port. An optically isolated 422/485 to 232 converter (model# 485OT9L) requires wall power and two twisted pairs to function effectively. For RS-232 DB-9 Male pinouts, key pins are 2 (Receive Data), 3 (Transmit Data), and 5 (Ground), with pins 2 and 3 crossed for PC connection. The Backbone DB9 Female uses pins 1 and 2 for Tx/Rx and pins 3 and 4 for termination LEDs, operating as a half-duplex connection. The Backbone RJ-45 pinout has a similar Tx/Rx setup as the DB9 but uses an RJ-45 connector. For 480 "Controller in" DB9 and RJ-45 pinouts, ensure balanced pairs for full duplex communication between 480, 480P, and 480R. Specific pinouts for 480P to 480R connections include power and communication lines. It is strongly recommended to use the cables provided by dbx to ensure reliable power delivery and signal integrity.
